I use a Terra handheld which is no longer made, is built
like a truck, and works very well. 

As a retired radio engineer, my guess is that you won't be
able to tell performance differences between any of the
available radios. Out in the boonies, receiver sensitivity
is about the only thing which will make a significant
difference - "name brand" radios will probably be slightly
better because they have been through multiple production
runs and were not designed and built in a garage. The
difference between one watt or two watts of transmitted
power is insignificant to reception by the ground station
and is often arrived at through "specsmanship." rather than
actual performance - it is also difficult to describe to a
layman how power is spec'ed and how different modulation
circuitry in the transmitter can make a less powerful radio
much more intelligible. The antenna will make a much greater
contribution to performance than the radio itself - a
permanently mounted antenna on the fuselage is much more
efficient than a "rubber-duckie."

In an urban area, some of the design features may make for
better reception and less interference from TV, FM, and
Pager
transmitters. Due to the nature of the AM modulation used
for aircraft communication, there will be little difference
between radios rejection of aircraft-generated interference
- the 'coupe ignition is shielded, so that's probably not a
problem.

It's probably best to buy a well known brand in order to get
service if needed. My most recent perusal of catalogs showed
me that there is actually little difference in cost if you
purchase all the accessories you need and use rechargeable
batteries. 

Consider how you will use the radio: 
Is it for backup or will it be your primary radio? How will
you power it? Rechargeable batteries "self-discharge" over a
period of a few weeks so they may render the radio unusable
just when you need it. Alkalines will last for years if not
used and thus are great for backup - they are what your ELT
uses. If it is to be your primary radio, powered by the
aircraft, why not purchase a used panel mount radio and get
easier to read displays, bigger knobs, and simpler
operation?
How will you listen and speak? There's not much room for an
antenna if you were thinking of holding the radio to your
ear - some radios require adapters to connect to your
headphones.

Each of the available radios has its own quirks:
King - it is a little more expensive, but probably works
real well.
Icom - receives VORs as well as comm. Well known in
communications. Probably pretty rugged.
Yaesu - New to aircraft but they make good comm gear too.
The limited controls on the radio may make it more difficult
to use.  Receives VORs.
Sportys - receives localizer as well as VOR. I haven't met
anyone who owns one. Costs the same as others after you buy
accessories.
Delcom - Have only seen a picture. The digi-switches are
very difficult to use, especially if you have small fingers,
they will drive you nuts. Terra used to use them and they
were their #1 repair problem.

Buying a radio for your plane is like many other consumer
decisions - a lot of compromises and advertising has to be
taken with a grain of salt.
